CHAIR.

Specification of Letters Patent.

Application filed August 4, 1916. Serial No. 113,078.

To all whom it may concern:

Be it known that I, WALTER I. KIRK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain'new and useful Improvement in Chairs, of which thefollowing is a. full, clear, concise, and exact description,referencebeing had to the accompanying drawings, forming a part of thisspecification.

My invention relates to chairs, and especially to collapsible chairs.

Prominent objects of the invention are to provide a simple and practicalconstruction of collapsible chair; to arrange so that the chair whencollapsed shall be very thin; to secure firmness when the chair is inposition to be occupied; to arrange to permit the chair to be easilyengaged and supported when in a collapsed position; to secure simplicityof construction and reduce the cost of manufacture; and to secure theforegoing and other desirable results in a simple and practical manner.

In the accompanying drawings Figure 1 is a view partly in elevation andpartly in vertical section of a collapsible chair embodying my presentinvention;

Fig. 2 is a similar view of the chair in a collapsed condition supportedin position upon a vertical wall or structure;

Fig. 3 is a front elevation of the chair in position to be used; and

Fig. 4 is a plan view of the same.

In the drawings there is shown a chair wherein the back 1 is mounted atthe upper ends of members 2 which extend downwardly and form the rearlegs 3. A cross member 4 extends between the legs 3. The seat 5 ishinged, as by hinges 6-6, tothe members 2, being conveniently secured toa cross member 7 extending between themembers 2 and forming the rearsupport for the seat 5. The front legs 8 are hinged, as by hinges 9, tothe front of the seat 5. Side braces or arms 10 are pivoted at 11 to thesides of the seat 5 and extended upwardly and rearwardly where theyengage pins 12 on the outer sides of the members 2, thus forming bracesand connections between the seat and the back. Other side members 15,

are pivoted at 16 to the rear legs 3 and have their other ends providedwith slots 17 adapted to engage pins 18 on the front legs 8 and therebyform braces for connecting the front and rear legs.

To collapse the chair the members 15 are elevated so as to disengagethem from the pins 18 and then the front legs 8 and seat 5 are swungabout the hinge connection between the latter and the member 7. Thismovement is continued until the seat comes into position against thefront of the rear legs 3, after which the front legs are swung upwardlyto the position of complete collapse shown in Fig. 2. In such completelycollapsed condition the seat 5 is substantially against the rear legs 3,the front legs 8 extend up in a substantially vertical manner upsidedown, in the rear of the seat 5, and the brace members 15 lie in asubstantially vertical position between the seat 5 and the front legs 8.The front legs 8 are set farther away from each other than the rear legs3, as shown in Fig. 3, and the cross member 20 between the lower ends ofthe legs 8, is so located as to pass down below the lower ends of therear legs 3 when the seat 5 and legs 8 are being swung down to collapsethe chair. Consequently said cross piece 20, when the chair iscollapsed, comes into position in the rear of the back members 2, asshown in Fig. 2. Thus the chair when collapsed has all of its membersextending substantially parallel to one another in very closearrangement, occupying very little space. Furthermore, the chair incollapsed condition may very advantageously be sup ported in a verticalcondition upon a vertical wall or other member, as shown in Fig. 2. Inthis condition the lower ends of the legs 3 may be mounted in sockets21. secured to a wall 22, and the cross member 20 may be insertedbetween two strips 23 arrangedabove and below said member 20. A catch 24ivoted to the upper member 23, may hold said member 20 against movementout of the space between said members 23.

In another application of mine executed of even date herewith, SerialNo. 113,076, trunks for harps or like instruments, filed August 4, 1916,I show a trunk for a harp or like instrument containing a chair such asdisclosed herein, said chair being mounted upon one of the flat sidewalls of said trunk in the manner shown in Fig. 2 herein. In

said other application I am claiming the arrangement of the trunk andchair or equivalent confining and supporting arrangement, whereas in thepresent application I am claiming the chair construction alone, the samebeing usable in connection with a harp trunk or otherwise.

It will be understood that changes and modifications may be made withoutdeparting from the spirit of the invention.

What I claim is:

A collapsible chair comprising front and rear legs and a seat hinged. tothe rear legs so that said seat may swing downwardly with reference tothe rear legs, and also hinged to the front legs so that said front legsmay swing upwardly toward said seat, the front legs being separated fromone another more widely than the rear legs and being connected by across member adapted 20 to pass below the lower ends of the rear legswhen the seat and front legs are swung downwardly about theirhingedconnections with the rear legs.

In witness whereof, I hereunto subscribe 25 Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,

Washington, D. G.
